This patchset is a proposition to improve a bit the code.
The changes are code cleanup and does not change the behavior of the
driver itself.

A couple a things call my intention. Why the cpuidle device is set for cpu0 only
and why the WFI is not used ?

Daniel Lezcano (7):
   ARM: OMAP4: cpuidle - Remove unused valid field
   ARM: OMAP4: cpuidle - Declare the states with the driver declaration
   ARM: OMAP4: cpuidle - Remove the cpuidle_params_table table
   ARM: OMAP4: cpuidle - fix static omap4_idle_data declaration
   ARM: OMAP4: cpuidle - Initialize omap4_idle_data at compile time
   ARM: OMAP4: cpuidle - use the omap4_idle_data variable directly
   ARM: OMAP4: cpuidle - remove omap4_idle_data initialization at boot
     time

The series looks fine to me in general. This clean-up is applicable
for OMAP3 cpuidle code as well.
Great!
However OMAP3 has a few specific things that cannot be removed as easily:
- the 'valid' flag is used because only certain combinations of power
domains states are possible,
- the latency settings can be overriden by the board code, so the
cpuidle_params struct is needed.

Right, I noticed that. I am looking for a way to have a similar cleanup for omap3 but without breaking the rx51 board.

Thanks

I want Jean to look at this series because some of his earlier
clean up has introduced those custom functions which
are getting removed in this series.

Thanks,
Jean
